When I joined the team, after an initial exploration of the application and features, I gathered all of the usability test and research results that were available for the product up until then. Upon studying them, I learned that while existing users enjoyed the service very much, new users experienced major orientation problems, some of them I could relate to, from trying to explore the app for the first time.

Together with the research results, I also received the previous designer’s files. Among them was a decision to add a clear call-to-action to the main screen. I liked that very much because now, instead of having to explore the app to get something done, the user would, in one tap, get a list of all the various actions he could take to clean and boost his phone’s performance. I stuck to this version for a while until, somewhere along the way, I realized that I had to keep the four original buttons available on the main screen to avoid damaging the experience for existing users.
